What is E-KIT
The E-kit is a modified version of THE COPENHAGEN WHEEL in which we have tried to eliminate all its limitations.
E-kit is a kit which will transform any random cycle into an electrified vehicle while keeping it cheap and simple.
We are actually dealing with design parameters of making this installation faster, sturdy and efficient.
The mechanism is basically a wheel which can be affixed to any bicycle at any moment on users demand, quickly.
Need of E-KIT
It can easily transform any common man cycle into an
electrically driven vehicle very easily.
Controllable assistance that can help the unfits start cycling
regularly.
Make it easer to travel further, regularly and carry more.
Gives extra help going up hills and cycling into headwinds.
Accelerating to cruising speed in a fraction of the time/ effort.
Costs a fraction of the price to buy and run compared to bikes.
Extra power in awkward situations makes cycling safer.
Why e-bikes not as popular in INDIA as in CHINA
Renowned for push bike culture.
Communist government can easily enforce measures to save environment.
Green ethics Advanced technology People are more concerned
about traffic.
Use of motorbikes is preferred
Measures cannot be enforced as easily in a democracy.
Not much concerned about environment.
Mediocre technology Not so enthusiastic
towards regulating traffic.

What is Copenhagen Wheel?
The Copenhagen wheel is a bicycle wheel that can easily retrofitted into any ordinary bike.
It’s sleek red hub not only contains a motor, batteries and an internal gear system, but also includes environmental and location sensors which are powered by the batteries in the wheel and provide data for cycle related mobile application.
Major Components of the Wheel
Working principle
The Copenhagen Wheel uses a technology similar to The KERS (Kinetic Energy Recovery System), which has revolutionized Formula One racing over the past couple of years.
When you brake, your kinetic energy is recuperated by the electric motor and then stored by batteries within the wheel.
It also occurs in exercise mode - where riders are working against the motor, thus giving themselves a workout and in turn recharging the batteries in the hub.
Goal of The Project
To reduce the rotating mass from the hub of the Copenhagen wheel.
All components should be placed in a single hub. The wheel must be easily retrofittable into any
standard bicycle. The bike must harvest energy through braking and
pedaling by choosing one of three modes:- i. off ii. Motor Assist iii. Pedal Assist (Regeneration/exercise mode)
The weight should be no more than a ‘heavy bike’ when fitted into a regular bike.
Advantages
Environment friendly.
Easily adjustable to any bike.
Doesn’t create extra load on ride.
Can be controlled by mobile phone.
Ensures rider’s health safety.
Encourages people to use cycle as a transport.
Disadvantages
Have to use a mobile phone to get full
functionality.
Not available worldwide, specially in
third world country like us.
Not cheap for people having low income.
Not good for too much hilly areas.

Methodology
1. CAD design-we will try to give the local
population an alternative to the mainstream
cycles. This is to be done by designing from
scratch the kit on CAD software.
2. Prototype analysis-a prototype will be built
which will basically transform the ‘hero’ into
a electrified vehicle while keeping it cheap
and simple.
Requirements
Motor Type: 24 volt, 400 watt continuous / 800 watt peak power
Battery Type: Dual 12 volt, 10 amp/hour, rechargeable battery pack
Recharge Time: 3-7 hrs (with outlet charger)
Top Speed: 15 MPH
Future prospects
Vehicle of future - Leading automobile companies are keeping their eyes on it.
Versatile application - Can be install in bicycle as well as in rickshaw and in other vehicles.
In mass production cost of manufacturing will drastically reduce.
Ford e-bike Ford unveiled its new e-bike as a study on urban mobility solutions.
The new Smart e-bike It will sell for under €2,900 in Europe.
Conclusion
The Copenhagen Wheel project began by asking the question: how can we improve the cycling experience in order to encourage more people to ride bikes. The same spirit rides in our hearts and surely it will fulfill the goal by attracting more people for safe cycling.
